I keep getting an error “Please Update Windows Defender Antivirus to the latest version KB4052623 ” The update has been installed a while back. Tried deleting all updates and reinstalled Defender, mpcmdrun.exe -signatureupdate and all that, still same error. Anybody knows of a fix apart from moving to 2019/2022

Fix :

Powershell : Install-WindowsFeature -Name Windows-Defender

CMD : “%programfiles%\windows defender\MpCmdRun.exe” -wdenable

Powershell: update-mpsignature
